Found this little blurb on this guy and I havent dug up any info on him yet. Sounds like he would could elevate in the draft...

...It has been reported that the Bears, Texans, Lions, Ravens, Redskins, and Chiefs have all shown an interest in Grand Valley State S Scott Mackey. Mackey led Grand Valley State in tackles (96) and interceptions (6). He also can return kicks evident by his 10.6 avg. on punt returns. The main concerns with him are a lack of speed (4.51 40-yard dash) and lack of size (5-11 185).
